Chennai: Aiming to make house building quicker and cheaper, the faculty members and alumni of IIT Madras have developed India's first 3D printing construction technology which could build a 350 sqft house within a week at a low cost.
This new technology is likely to revolutionise the construction industry in the country by reducing the time and manual labour while building houses.
“Usually, a concrete layer will take minimum 28 days to 30 days for curing. But, in our innovative technology, the concrete will set in 3 to 5 hours,” says Vidyashankar C, one of the co-founders of Tvasta Manufacturing Solutions, the start-up which has developed the technology along with IIT Madras faculty members.
IIT-M and Tvasta also established 3D printing lab to take the indigenously developed technology to the market.
The team has done innovation in raw materials to make concrete set very fast.
The 3D printing construction technology includes four aspects - software, raw materials, printer and delivery system.
“After constructing the house on the computer using 3D modelling, if we feed it to the printer, then, the delivery system will bring out the component through the printer. The component either could be a house or a part of the house,” he explained.
“In the 3D printer, we can also get all shapes in the concretes. Whatever, the computer designs, the printer will bring out that form on concrete,” he said.
“3D printing of concrete gives a new dimension to construction. This technology can best meet the complex demands of modern architecture with concrete,” says Prof Manu Santhanam, department of civil engineering, IIT Madras.
The team of four students from IIT Madras - Adithya VS, Parivarthan Reddy, Vidyashankar C Santhosh Kumar - has founded Tvasta Manufacturing solutions, an additive manufacturing start-up.
They developed the 3D printing construction technology and 3D printer along with the faculty members in three years.
The start-up aspires to completely automate construction, including placement of reinforcements and finishing, by re-envisioning the construction process
“We will be building India's first 3D printed house within the next one year. The impact of 3D printing in construction will be primarily focussed towards the “Housing for All” scheme,” says Adhithya VS, one of the co-founders of Tvasta.
At present, the start-up has come up with a proto-type 10 X 10-metre 3D printer. It is only a prototype and soon the team will come up with a bigger printer to enable it to build a house.
“Due to the reduction of time in house building and less requirement of labourers, the building cost would come down. The operation of printers also would create skilled labourers,” says Vidyashankar.
Though the cost of the building and construction time would come down, the durability of the building will be more than the conventional building. “By using the technology, a conventional house can be built within a month at a comparable cost,” he observed....
